Alright, I just installed me fiberglass box... Its bad as hell.... One problem, i got 2 10" hx2's... One is brand new and one is almost 2 years old(from my old set up) I am sure the new one needs a little breaking in, but I am talking, it doesnt move.... The other one is jumping like crazy and hitting really hard... They both are wired mono and are doing the same thing, but the old one is hopping like carzy, and the new one can just be felt.. Not visually seen... I am sure this is normal... Till the other one is broken in.... But I would like to hear what you guys think... They are 4ohm DVC subs and they are wired mono in series to the smote of 4 ohms... Everything is good wiht them... They work togehter and fine... can hear them going as i type... How long is break in period? and is this normal? I am sure it is, but just want some info...

 

I would bet that the one that isn't moving doesn't work or isn't hooked up. You should be able to see it moving. Right now it is acting as a passive radiator and only reacting to the sound waves produced by the good sub. Unhook your good sub and try running just the new one. My guess is you won't hear anything.

 

sounds like you have a wiring problem, amp not configured correctly, or bad sub.

 

wired out of phase ?

 

Pull the woofers and check the wiring. Even if it's new it should be moving like the other one. It's either not connected at the sub or not connected at the amp. And if it is connected then you have a dead sub.

 

dont wire them up as mono, wire them up as parallel, sounds way better.

 

care to expain that one skippy?

enjoy.

 

Thanks for the link, but I already passed my circuits class about 6 years ago

The point is that your statement above makes no sense....If you take two subs and wire them in either series or parallel, you have wired them in mono!! Mono means one...meaning that you have wired the subs to be powered by one channel.

It makes no matter how you wire them together, so long as the nominal impedance of the subwoofers when wired together is matched to specs on your amp.

BTW, that's a good link, as theres lots of good info in there. You can also head to the tutorial section at JL Audio. They have lots of good wiring diagrams as well.

 

Hey how about trying to wire them up parallel and mono!!!!! Think you could do that???? Then that would bump, huh??? Parallel refers to the coils on the subs where as mono would refer to how the speakers are hooked to the amplifiers. Oh yeah and parallel doesn't always mean it sounds better. Try hooking two Dual 2ohm subs in parallel to a amp that's stable at 4ohms. Won't get much sound just some magic smelly smoke from the amp!!!!!
